Description:
------------
db2_procedures & db2_ procedure_columns does not work when connected with a persistent connection. When looking at the CVS I noticed that these two functions were retrieving the DB2 connection with the ZEND_FETCH_RESOURCE function while all the other functions used ZEND_FETCH_RESOURCE2 to get the DB connection. I updated the source to mimic the other functions and it works great now.

P.S. - The functions work fine when db2_connect is used instead

Reproduce code:
---------------
$cnx = db2_pconnect('db', 'user', 'pass', $options);
$r = db2_procedures($cnx,NULL,'SCHEMA','%%');
print_r(db2_fetch_assoc($r));

Expected result:
----------------
Array
(
    [procedure_cat] => 
    [procedure_schem] => SCHEMA
    [procedure_name] => PROCNAME
    [num_input_params] => 2
    [num_output_params] => 1
    [num_result_sets] => 0
    [remarks] => 
    [procedure_type] => 1
)

Actual result:
--------------
Warning: db2_procedures(): supplied resource is not a valid Connection Resource resource

Warning: db2_fetch_assoc() expects parameter 1 to be resource, boolean given
